The design and implementation of strategic plans in Primary Schools / A case study of two Mahikeng area office Primary Schools
(2011)A strategic plan is the physical document that embodies the guiding orientations about how to manage the education system within a larger national and local development perspective. Such a plan can lead to school ... -
Design and In vitro analysis of polyethylene glycol based multidrug delivery systems for combination therapy in the treatment of Breast Cancer
(North-West University (South Africa), 2018)Polymer hydrogels are known to be excellent drug delivery biomaterials for unconventional cancer therapy. The polymer hydrogel was prepared via the free-radical polymerization of acrylamide (AAm) in the presence of poly ... -
Design and operation of an ammonia-fueled microchannel reactor for autothermal hydrogen production
(Elsevier, 2018)The present work describes the design and operation of an autothermal microchannel reactor for portable and distributed hydrogen production via ammonia decomposition. The microreactor consists of an array of alternating ... -
The design and operational behaviour of a laboratory scale fixed-bed gasifier
(North-West University (South Africa) , Potchefstroom Campus, 2016)Fixed bed coal gasification and combustion operations form an important part in the global energy supply, and these processes are characterized by complex interactions which are difficult to study on an industrial scale. ... -
The design and optimisation of a bubble pump for an aqua–ammonia diffusion absorption heat pump
(North-West University, 2012)Energy shortages around the world necessitated research into alternative energy sources especially for domestic applications to reduce the load on conventional energy sources. This resulted in research done on the possibility ... -
Design and optimisation of a PCB eddy current displacement sensor
(SAIEE, 2017)Position sensing is one of the crucial parts of many systems, specifically in an active magnetic bearing. The position is used to control the magnetic forces within an active magnetic bearing to keep a rotor levitated. ... -
Design and optimisation of a solar thermal powered Aqua-Ammonia diffusion-absorption heat pump cycle under seasonal variance for residential use
(North-West University (South Africa)., 2021)The diffusion-absorption refrigerator was patented by Von Platen and Munters (1926). The conventionally low coefficient of performance and the high driving temperature have been the focus of most research since its ... -
Design and optimisation of new beamlines for iThemba laboratory for accelerator based sciences (iThemba LABS)
(North-West University (South Africa), 2002)The facilities at iThemba LABS are used for basic and applied research, treatment of patients with proton and neutron beams and the production of radioisotopes for hospitals and industry. The laboratory operates a 6 MV ... -

(North-West University (South Africa), 2002)The facilities at iThemba LABS are used for basic and applied research, treatment of patients with proton and neutron beams and the production of radioisotopes for hospitals and industry. The laboratory operates a 6 MV ... -
Design and optimization of an intermediate heat exchanger in the Eskom advanced high temperature reactor
(North-West University (South Africa), 2019)The Eskom AHTR forms part of the next generation of nuclear reactors and aims to have a load following capability by storing heat in molten salt. The heat generated in the reactor is removed by Helium gas and should be ... -
Design and Synthesis of a Robust Power Supply for Harsh Environments
(North-West University (South Africa), 2019)Research and control applications often takes place in harsh environments where equipment is exposed to less-than-ideal environmental conditions. This dissertation relies on a proven engineering process to design and ... -
Design and synthesis of an image-based object detection system
(North-West University (South Africa), 2020)This thesis presents the design and synthesis of an image-based ob-ject detection system, as applied to a facial recognition (FR)-enabled surveillance system. By employing the Design Science Research (DSR) paradigm and ... -
Design and synthesis of dual acting carbamate inhibitors of acetylcholinesterase and monoamine oxidase
(North-West University (South Africa) , Potchefstroom Campus, 2017)Alzheimer’s disease (AD), the most common neurodegenerative disorder, affects about 10% of the population over the age of 65 years. The disease is typified by symptoms such as memory loss and impairment in abilities including ... -
Design and synthesis of heterocyclic compounds for neuroprotective enzyme interactions
(North-West University, 2010)Neurodegenerative diseases are thought to be multifactorial in nature and therefore current research focus has shifted from a ‘one-drug-one-target’ approach to that of multitarget directed ligands (MTDLs). These ligands ... -
